SPECIFICATION forming part of Letters Patent No. 606,385, dated .TuneA 28, 1898. 1 E, fApplio'ntiun filed November 2, 1897. Serial No. 657,144. (No model.)-

-To wZZ whom, it Duty concern:

Be it known that I, GUs'rAr EMIL BESSE, a resident oi the Icity of lrooklyn, in the county of Kings and Stato of New York, have `tionarylamps, is more espeeiallyintended forA lamps which are portalde.

A lamp embodyingmy invention comprises a receptacle l'or carbid, which constitutes the generator, and a reservoirl vl'orwater above said receptacle.

The principal object of the invention is to obtain an even and. controllable supply of water to the carbid, and for this purpose I employ between the water-reservoir 'and the carbid-receptacle below it one or more wicks, through which the water is supplied from said reservoir to said receptacle by gravitation in a constant, but restricted, iiow instead of intermittently, as when it is supplied in drops, the result of such constant I iow being a steady flame instead of a flickering one. p

Figures 1 and 2 represent vertical sections .taken at right angles to each other, of a lamp embodying my invention, the section Fig. 2 being taken in the line 2 2 of Fig. l. Fig. 3 represents a vertical section taken in the line 3 3 of Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

`A designates the receptacle for the carbid, which constitutes both the base of the lamp and the generator and is represented as .en-

veloped by a jacket A', containing some ma-` terial which is apoor conductor of heat.

l is the water-reservoir, consisting of a closed vessel, the lower part of which is screwed into a socket in the head of the carbidreceptacle A and forms a removable cover thereto. This reservoir B is represented as surrounded by a jacket B', containing some material which is a poor conductor of heat.

C designates the burner, which will be hereinafter spoken of as the. main burner, between which and the carbid-receptacle there is apipe I), which passes water-tight through the bot-tom of the'water-reservoir13 and is open to theV upper part of the carbid-receptacle. The burner and the upper part of the pipe D are represented as supported by a pillar E, which I prefer to make of some poor heatconducting material--poreeluin, for example.

F is a wick-tube `represented (see Fig. 2) as having two branches, both branching from a.

cock G within the water-reservoir and extending downward through the bottom of said reservoir into the upper part of the carbid-receptacle. At the bottom of thiscoek, be

tween the wick-tnl les, there is a nozzle or short tube u, which reaches nearly to the bottom `of the water-reserwiir l. The cock G is represented as what is known as a three-way"4 cock, which inaybe'brought to a position to open both wickftubes to the short tribe a, as shown in Fig. 2, to allow water to flow from the reservoir ll through said tube (l, the cock G, and the two wicks I, the upper parts of which are contained in the tubes F and the lower parts of which hang below the said tubes into the carb irl-receptacle, the onl y communication between the water-reservoir and the carbid-receptacle heilig through these wicks,whicl1 so restrict the natural downward -flow of the water by gravitation as. to enable its supply to be better regulated by the cock yGr than it could be without the wicks.

Between the pipe D, which may be termed the gas-conduit, and the burner C there is l a cock J for the purpose of shutting O'Il the gas fronrthe burner. This cock .l hns such a connection with'the cock G that when the said cock .I is open to the main burner Cto .supply the latter with gas [or illumination,- as shownin Figs. l and 2, the cock G is also open to the tube a and wick-tubes F, as shown in Fig. 2, so that the water is then supplied to the carbid in the receptacle A for the gen- ,eration of the gas, which theirflows-through the pipe D to the burner. The same connection between the two cocks causes the cock G to shut olf the supply of water tothe wicks and the carbid receptacle when `the cock J is turned to a position to shut olf` the gas from the pipe D to the main burner C. 'lfhe con nection between the two cocks may be made by any means by which the two are made to. operate as above described. It is represented as consisting of an eccentric l) on the plug of the cock .I and a-rod c, connecting said eccen- .trie with a short lever d on the plugiof the cock G, the said lever cpl being within the Water-reservoir, and the said rod c passing freely through a small hole in the top of the said reservoir, the said hole serving also as a vent for the admission of air to said reservoir.

In order to provide, after the gas is shut olf' from the main burner C and the Water is shut off from the carbid-receptacle, for the combustion of the gas which continues for some time to be slowly generated in the receptacle A, owing to the moisture remaining in the carbid, I provide vin the plug-seat of the burner-cock J on one side of the plug of said cock a small cavity e, Fig. 1, from which there are small holes or passages f, (see Figs. 1 and- 3,) leading from the upper part of the said cavity through the shell of the said cock to a point near the main burner C, and I construct the said cock as a three-Wayfcoek, as shown in Fig. l, so that when the gas is shut off from the main burner/C it may be turned onto the cavity e and may issue in a jet or jets through the passages f, at the outer oriiices of which it may be burned. Thus the lmrnr-r-eoek is not only made to perform the function of a safety-valve, but the passages f constitute a supplementary burner for the burning of the gas which escapes through it while it is performing that function, and the offensive odor which results from letting it escape through an ordinary safety-valve is thus got rid of.

I have represented as provided around the passages j' a cap 71 which will serve to prevent the accidental blowing out of the flames ol" the small jets issuing from the said pas sages, the said cap having holes t' around its lower part for the admission of air to said jets and openings j at the top for the escape of the gases of the combustion taking plac'e from'said jets. This cap is, however', not absolutely essential to the carrying out of my invention. I have also represented in the shell of the burner-cock a by-pass g, which is constantly kept open, so that there maybe a srnall fiame supplied by it for igniting the jets from f f when the passage to the main burner is closed.

What I claim as my invention is- 1. The combination with the carbidreeep. taele and the Waterreservoir above it, of a wick-tube having a plurality of branches between said receptaele and reservoir and a cock in said wick-tube for controlling all itsV branches, substantially as herein described.

2. In an acetylene-lamp, the combination of a carbid-receptacle constituting a generator, a Water-reservoir, a water-cock between said reservoir and said generator, a main burner vand asupplelnentary burner supplied from said generator, a gas-cock common to both of said burners for opening either when the other is closed, and a connection between the said cocks for .opening and closing' the water-eoelcand thelnain burner simultaneously and for closing or opening the supplementary burner while the main burner and the Water-cock are respectively open or closed substantially as herein described.
